OVONIC 4S 10000mAh 14.8V 130C LiPo Battery 2-Pack EC5 + Voltage Checker for 1/5-1/8 RC Models

Overview

The OVONIC 4S 10000mAh 14.8V 130C LiPo battery combo is designed to provide high-current power for large-scale RC models. This set includes two 4S1P packs with EC5 plug plus a LiPo voltage checker/buzzer alarm for monitoring cell voltage during use, helping reduce the risk of over-discharge.

Key Features

• High output rating: 130C discharge rate for demanding RC driving, boating, or large-model flight setups.
• Large capacity: 10000mAh per pack for extended runtime.
• 4S configuration: 14.8V nominal (label also shows 148Wh).
• Connectors and wiring: EC5 main connector, JST-XHR-5P balance connector, and 12 AWG leads.
• Voltage monitoring included: Voltage tester buzzer alarm helps check cell status and low-voltage warning.
• Manufacturer-stated cell construction comparison: “Stacking Technology” is claimed to provide higher energy density (+6%), longer running time (+12%), lower battery swelling (-8%), and lower internal resistance (-4%) versus “Winding Technology (Others)”.

Safety & Charging Notes

• Ensure compatibility by matching voltage, dimensions, and plug type with the RC model.
• Stop charging immediately when any cell reaches 4.2V (normal range: 3.7V to 4.2V per cell).
• Inspect the battery condition before each use.
• If a new battery does not hold a full charge or loses charge rapidly, use a balance charger and cycle it several times.
